Description

thawing cabinet for frozen meat

technical field

The invention relates to the technical field of thawing devices, in particular to a thawing cabinet for frozen meat.

Background technique

Thawing is the reverse process of freezing. Freezing is to turn the water in the food into ice, and thawing is to turn the ice into water. The speed of thawing will affect the quality of the food. For ordinary frozen food, if the thawing speed is too fast, It will cause the water in the intercellular space (that is, outside the cell) to have insufficient time to "flow back" into the cells, thereby causing the loss of juice and reducing the quality of food. It should be noted that the quality of thawing effect is not only related to time and food quality. , which is more related to the edible safety of thawed food;

When the food is frozen, the activity of the microorganisms in it is basically inhibited. However, during the thawing process, as the temperature rises, the microorganisms begin to recover and the activity is enhanced. Generally, the temperature range suitable for the growth and reproduction of microorganisms is 5-60°C. ℃, if the thawing process is always in this temperature range, it will undoubtedly increase the safety risk of food;

Existing thawing methods include natural thawing, warm water thawing, steam thawing, refrigeration thawing and microwave thawing and other thawing methods:

Refrigeration and thawing By placing meat products in an environment of about 4 °C for a long time, the quality after thawing is better, but the thawing time is long, and natural thawing is not advisable because it is in the range of 5-60 °C for a long time. Compared with natural thawing, the thawing temperature used in warm water thawing is the same as the optimal reproduction temperature of microorganisms, so this thawing method is also inadvisable. Steam thawing uses steam (the temperature is usually higher than 60 ℃), although the thawing time It is short, but on the one hand, excessive temperature will make meat cooked and fruits and vegetables soft. Microwave thawing uses the nature of water molecules to rotate under the action of an alternating electric field to generate frictional heat to thaw food. Its thawing speed It is relatively fast, but it is prone to overheating effect. That is to say, when using microwave thawing, it may happen that the inside of the food has not been thawed, but the outer surface has been overheated, and overheating will cause protein denaturation or tissue structure. food quality.

A food thawing device with an application number of "CN201821543217.7" in the prior art includes a thawing cabinet, and both sides of the outer wall at the bottom of the thawing cabinet are bonded with gaskets, and the gaskets are respectively located at the four corners of the outer wall at the bottom of the thawing cabinet , the thawing cabinet is composed of a water storage chamber and a thawing chamber, and a filter screen is arranged between the water storage chamber and the thawing chamber, a heater is provided at the bottom of the water storage chamber in the middle position, and the bottom of the water storage chamber is located in the middle. A water inlet is opened on one side of the outer wall near the top, and the inner wall of the water inlet is provided with a water inlet pipe, the interior of the water inlet pipe is provided with a shrapnel, and the top of the water inlet pipe is welded with a water inlet bucket, and the outer wall of the water storage chamber is provided with a water inlet. A liquid level gauge is arranged on the side away from the water inlet pipe. The above-mentioned device can speed up the circulation speed of water vapor, so as to facilitate the rapid thawing of food, and can turn the food over to speed up the thawing speed. waste of resources.

However, the above-mentioned food thawing device still has obvious defects in the use process: 1. The above-mentioned device heats the frozen object through the heat generated by the steam. However, in the actual production process, the temperature of the water vapor is relatively high, and the water vapor is in the freezing process. The condensation on the surface of the product will release heat, and the higher temperature is easy to ripen the surface of the meat product. At the same time, because the temperature is conducted from the surface to the inside, during the thawing process, the temperature inside the meat product is usually between 20-50 °C. The temperature is the best temperature for bacteria to grow, so the above thawing method will not only destroy the surface of the meat product, but also cause the bacteria inside the meat product to multiply, thereby reducing the storage time and quality of the meat product; 2. The thawing method of the above device is relatively Single, it is impossible to thaw scientifically and efficiently, and it is difficult to guarantee the quality of meat products after thawing.

The microwave generating device 19 cooperates with the microwave thawing hole 17 through a microwave reflection pipe 21, and the air-drying blower 20 cooperates with the air-drying hole 18 through a pipe.

The hydraulic telescopic cylinder 5 telescopically drives the turntable 3 to expand and contract, and the rotary motor 10 rotates to drive the turntable 3 to rotate, so that every time it rotates, there is always a defrosting box 8 located at the highest point and the lowest point. It is matched with the top of the cabinet 1, and the top of the cabinet 1 is in close contact with the thawing box 8, so that the microwave generated by the microwave generating device 19 is used to heat the frozen meat inside the thawing box 8. After heating for three minutes, the air-drying blower 20 drums The surface of the frozen meat is air-dried by entering gas, and the quality of the frozen meat inside the thawing box 8 is detected by the quality detection device 6. When the quality is somewhat lighter than the previous detection, the freezing step needs to be repeated. When one thawing box 8 is at the highest position, one The thawing box 8 is at the lowest point, and the bottom of the cabinet 1 is filled with clean water. In this way, the meat products inside the thawing box 8 can be cleaned and thawed at the same time.
